Capture the real-time EDID of the AVR with the TV connected (PC-AVR-TV), i. e. the merged EDID by the AVR from the TV EDID. The audio block is in the 'HKR,EDID_OVERRIDE,"1", ...' line. If needed use Extron EDID Manager to find it.

[UPDATE 12/6/2013]

The problem with the driver reverting to 2 channel audio (or no audio) due to hotplug detection (switching inputs on TV or AVR, HTPC waking from sleep, or powering up order of components) can be fixed by following the procedure explained by Ryan L in this post.

Only passthrough of compressed audio (e. g. AC3, DTS) is possible, so it's for the application (Video Player setup, encoding, filtering, like with AC3Filter, or even DDL = Dolby Digital Live for games) to take control of how audio is sent through the HDMI link.

NO EDID override can "fix" the bandwidth limitation, and it willl only be required if there is a bad EDID detection of DD or DTS capabilities, but never for the 2 channels limitation.

UPDATE[12/29/2011]

Everyone with a 3DTV + HDMI1.3 AVR: please check first this post by renethx.

In sum, 2 separate connections and NO EDID Override needed.

UPDATE[2/5/2011]

So, according to this case an EDID override can be used to pass full 3d through an HDMI1.3 AVR. Then a 3DTV and a 3D capable graphic card are all you really need to get 3D with an HTPC.

Without an EDID override solution would be, of course, 2 connections, one for video to the 3DTV, and one for audio to the HDMI1.3 AVR.

UPDATE[8/31/2010]:

===============================

There's still an issue with EDIDs with no 8-LPCM SAD. So if your AVR is 5.1 only or the EDID lacks an 8-LPCM SAD an EDID override will be required to bitstream.

If installation is messed up somehow, a clean install with minimum codecs (just ffdshow) + MPC HC or one of the commercial players is the best way of making sure that bitstreaming of HD audio works.

Then add other applications and test one by one so as to be able to successfully debug each particular issue.

However, EDID overrides are still needed for dealing with other EDID issues. As this first post has general information for installing/uninstalling, capturing and troubleshooting EDID overrides, and to not replicate the same information elsewhere, I will be using this post to address these. For general EDID overrides requests there's already a dedicated thread.

I will leave the rest of the information in this post, even the table of EDID overrides, as they can be used in fact for specific configurations. Only modified info in most cases is the TrueHD SAD, so they shouldn't affect video functionality.

1. EDID CAPTURE

The EDID Override mod for solving the bitstreaming and/or video handshake issues on the 5xxxs is usually made up by a combination of the display device video data stored in its corresponding EDID + the audio descriptors of Onkyo TX-NR906 EDID that solves the bitstreaming issues + rest of information stored in the AVR/AVP EDID.

So, the 2 EDIDs (display device & AVR/AVP) are required to do the mod. Also

the full REAL-TIME (no registry entries) 256-byte EDIDs are required (for Moninfo check that a 'HKR,EDID_OVERRIDE,"1", ...' line is present in the generated .inf file). There are 2 tools for capturing the full 256-byte EDID:

Entech utility Moninfo. New version of Moninfo (2.44.0.825) can now capture the full 256-byte EDID on 5xxx cards.

GetEDID, kindly developed by AVSForum guru, vladd, who's also author of EDID Editor, an indispensable tool for doing these mods (EDID Editor is the only tool that I know that can calculate the EDID checksum ... double thanks, vladd, ). This utility works for all ATI cards. To download it and for a description of the utility and how to use it see this post by vladd.

WARNINGS: getEDID does not currently capture the REAL-TIME EDID, but the EDID of the active display device(s). Use preferably moninfo to capture the REAL TIME EDID.

If UAC is active Moninfo must be run as administrator.

Here's the procedure for connecting and capturing the full 256-byte EDID.

Make sure that the .inf driver is the ONLY one in its dir
Browse my computer for driver software [Select]
Let me pick from a list of device drivers on my computer [Select]
Have Disk [Select]
Browse to the directory where .inf driver is located.
Click on .inf file and then on the Open button
OK [Select]
Next [ Select]
Confirm installation if necessary ([Windows Security] Install this driver software anyway)
Close [Select]
REBOOT

Alternate method

If you have more than 1 monitor setup you most probably will have more than one "Generic PnP Monitor" device in the Monitors tab. Use this alternate procedure for these cases.

3. TIPS FOR TROUBLESHOOTING BISTREAMING AFTER INSTALLING THE OVERRIDE.

DTS HD should bitstream first time on MPC-HC/ffdshow, TMT3 .170 or WinDVD2010. If you can't bitstream TrueHD then there's a problem with the EDID override.

Check that the override is actually installed. Go to Device Manager->Monitors[Expand], and verify that description for the override is actually there.

Don't forget to REBOOT after install.

NEVER try to test bitstreaming first time on WMP or WMC! Use any of the commercial players or MPC-HC/ffdshow.

Verify that to your AVR/AVP is set to "AMP" mode, i.e, to NO audio-passthrough of your display device. Also, if it is the case for your DENON AVR, try setting "2.3.4 Auto Surround Mode" to "OFF", but it doesn't work in all cases.

Avoid using Haali Matroska Splitter if MPC-HC is your player (at least while testing bitstreaming first time).

Avoid setting the "Enable GPU scaling" option in CCC as it affects detection of refresh rates.

4. UNINSTALLING THE OVERRIDE.

Go to Device Manager

Monitors[Expand]

Right-click on the override

Select uninstall

Tick on "Delete the driver software for this device"

OK

Reboot

After installing/uninstalling your EDID override make sure to reset the TV as well as the receiver so they can redo their handshake.

NOTE: On board menus of some AVRs (e.g. ONKYO) will not appear on resolutions less than 720P.

Make sure to delete all leftovers from the system:

Start [Select]

My Computer [right-click]

Properties [Select]

Advanced System Settings {Select]

Environment Variables [Select]

New [Select] (Under User variables ...)

Set field "Variable name" to devmgr_show_nonpresent_devices

Set field "Variable value" to 1.

OK [Select]

OK [Select]

Now go to Device Manager (Start->Computer->Properties [right click])

Menu option "View" [Select]

Menu option "Show hidden devices" [Select]

Monitors [Select]

Uninstall any greyed-out display device.

Tick on the option "Delete all driver files for this device" (if applicable)

5. EDID OVERRIDES

As a general criterion to pick the right mod for you:

Just base your selection on the display device. If you don't find your specific model, try one similar. If no similar device is available then try by general type (LCD, Plasma, DLP or projector). If no alternate option works for you (because of video issues) then ask for a custom mod.

For the AVR/AVP part select according to brand,regardless of the specific model, as any mod will resolve the bitstreaming issue. You could even install a mod for your display device, or similar, and choose another AVR/AVP brand.

The bitstreaming issue with ATI 5xxxs cards was due to 192kHz audio sample rate being DISABLED in the EDIDs of DENON, SONY, and some ONKYO AVRs/AVPs (for an excellent introduction to the EDID standard read this page by Extron).

An AVR EDID is a 2 128-byte data blocks structure: a Base block and an Extension block. Within the Extension block an Audio Data block is located, made up of individual Short Audio Descriptors (SADs):

Not all ONKYOs in a failing series exhibit the TrueHD problem.So if you own a DENON (except the AVR 2808CI) or a failing ONKYO, checking DTS HD bitstreaming (with MPC-HC, TMT3 .170 or WinDVD2010, but not possible with PDVD9/10 though) is a first test to make sure that your installation is OK. You will then require an EDID override only for bitstreaming of TrueHD.

But if you own a possibly failing ONKYO, as not all ONKYOs in a "flawed" series exhibit the TrueHD problem, check that TrueHD works first.

So even if the issue is not ATI's, they could still produce a fix so that everyone can bitstream on the 5xxxs without needing an EDID override. So post a feedback to ask them for the fix, and even leave a link to this thread, by going to the following page:

Of course DENON and SONY should be contacted about this problem and also be referred to this thread, so that they fix it for future products, and release firmware updates ASAP for current AVRs/AVPs for which it can be applied.

WHAT THESE MODS FIX FOR BITSTREAMING

With DENON, SONY, and some ONKYO AVRs/AVPs with NO override:

You won't get the third option on audio settings of PDVD9.

You'll get no TrueHD on MPC-HC/ffdshow, TMT3 .170 beta update or WinDVD2010.

DO YOU REQUIRE A CUSTOM MOD FOR YOUR DISPLAY DEVICE-AVR/AVP?

For most cases the (*) mods will work, so if you don't find the specific mod for your HDTV/AVR combination, try these first.

Please understand that I'm currently the only one doing these mods so ask for a mod only if:

Of course your AVR is a DENON, SONY or a failing ONKYO (see point 3).

PDVD9 is your only player and you don't get the third option on PDVD9 audio settings.

You can bitstream DTS HD (no TrueHD) on either MPC-HC, TMT3 .170 or WinDVD2010 without the override. If you can't there's an install problem to troubleshoot or that the AVR HDMI has to be set to "AMP" (no TV audio pass-through). So DO NOT ask for a mod if you use any of these players and you don't pass the DTS HD test first.

You have video issues as your Display Device, or a similar Display Device (LCD, Plasma or Proj.) and AVR/AVP combination for your setup is not listed.

Problems requiring a custom mod are all video related as the audio block is the same in all mods. If video data from EDIDs on the list conflicts with your display device specs, then you could run into video issues such as:

Thanks for this service - recall my scenario was with a Sony projector, so enclosed are the INF's for the VPL-VW85 and the Denon AVP A1 (though you have the one from JonFo for the A1 so I guess you could use that as well)

i'm new to this board and just wanted to thank tulli!
i got my hd5450 last week and wondered why i didn't get the hd-audio to my denon avr1910.
now it works with the Panasonic TV - ONKYO TX-SR606 override!
thank you so much, tulli!

Thanks Tulili, will try it tonight after work. I did have bitstream problems and audio, got bitstream to work and NO video when I open folder to play via TMT3. It's very odd thou, I can play, a very sh*tty, banding etc video while opening file with TMT3, but no bitstream..

Thanks for your work on this Tulli - seems to be working fine (the only issue I see is 5.1 lossy DTS tracks are playing side channel information out of the rear channels in my 7.1 setup, but I think this is a Arcsoft/Microsoft issue and nothing to do with your EDID.

Thanks so much for doing all this. I have a sharp 46" lcd and a sony str-dh800, so I tried the one labeled 'Should work for most LCD TVs + DENON AVR' and it actually did! I was able to bitstream and get dts-hd on my receiver using my 5450. However, I lost the CCC option for 1080p resolution 1920x1080@60Hz). The only option I have now is for 30Hz (1080i). So, I'm figuring that as you said, I have an issue with that mod. Is it possible to get one that will allow me to have the 60Hz option? Looking at the instructions, I don't think I'm going to have the ability to get the files for you Tulli, otherwise I'd just go for the total custom job.

Hello, I'm from Spain,I have seen the work you do and is incredible, I have a sony lcd 40W2000 and sony STR-DG820 amp, catalyst detects it as SONY AVAMP, I would be grateful if you helped me, THANK YOU

That's definitely a known issue with the (*) EDIDs. You may try any of the other LCD mods.

Of course you can also post the full 256-byte EDID of both the Sharp & the Sony AVR and I'll do the mod for you (is that a Sharp Aquos?, as I have one on my HD).

"¡Hola, saludos a todos ustedes por allá en España!"

You may try any of the two available SONY LCD + DENON AVR mods. They should work fine for you as the only critical element audio-wise is the audio block, which like I explain on the OP, is the same for all mods.

The only "glitch", if you may call it so, is that you will see a "DENON AVAMP ..." description for your monitor. If that bothers you then post the 256-byte of both the LCD-TV and AVR and I will do the mod.

It is an Aquos but since I only have the 5450 and it won't work with Moninfo, it doesn't look like I'll be able to pull the full EDID for ya. I will try one of the other ones and see if I have better luck. Thanks!

As a brief aside - who "owns" that problem? To me, Arcsoft (or whoever's player) needs to properly assign the channel information...using Reclock has become more complicated with the beta 170 of TMT, so that solution is less useful...

Right now I have a PC setup with the BeyondTV software to record various TV shows and it will wake itself up from standby, make the recoding and then go back ito standby until it is time to make another recoding or we wake it to watch the recorded shows. The PC is connected via HDMI cable to a Toshiba 52LX177 HDTV through an Onkyo TX-NR906 AVR from the DVI port of a "SPARKLE P980X+ GeForce 9800 GTX+ 512MB" video card.

To get the "wake from standby while the TV/AVR are off" from reverting the active video port to the VGA from the DVI (because the PC receives no EDID info from the TV/AVR when those devices are off), I had to buy and install a Gefen DVI Detective between the AVR and the PC. This was needed so that the TV's EDID information was always available to the PC when the PC woke up looking for it.

Is it likely that this override will fix this reverting to VGA issue if the Gefen device were not used?

I'd like to try a "HIS H567Q512 Radeon HD 5670 (Redwood) IceQ 512MB" video card and use its HDMI (rather than DVI) port but if I do that I would either need a functional override or to buy a Gefen HDMI Detective.

No, the override is only good to force a certain EDID when needed, as it's the case with ATI 5xxxs drivers natively not parsing well the audio block from some AVRs. But the AVR connection will not be active if you turn it off, even with the override.

So if you get the 5670 a Gefen HDMI Detective Plus will be required for your setup.

I have a JVC HD750 projector and an Onkyo 905 Receiver. I've attached the 2 inf files (in a zip file) I created a while back with Monifo. I believe they're in the correct format because I created them over my mobo HDMI connection before I got my ATI 5450. I'd greatly appreciate it if you could do the EDID mod for me. Many thanks.

Separately, I actually connect my htpc to an HDMI splitter and then have feeds from the splitter to various devices including the JVC projector and LG and Samsung TVs. Should this still work in this scenario (JVC is the key device!)? Thanks.

No need to override the Onkyo 905 EDID as the audio block is exactly the same as the 906's I'm using for the mods.

Hi. Thanks for the speedy response! Sorry for the next question but I'm not 100% clear on all this stuff, even after reading the forums. Are you saying that the JVC projector (video) part doesn't matter, and that if I just take one of your existing mods (which includes the 906) it should work fine with my 905?
